Extensive epigenetic reprogramming during the life cycle of Marchantia polymorpha.

ABSTRACT:

Background

In plants, the existence and possible role of epigenetic reprogramming has been questioned because of the occurrence of stably inherited epialleles. Evidence suggests that epigenetic reprogramming does occur during land plant reproduction, but there is little consensus on the generality and extent of epigenetic reprogramming in plants. We studied DNA methylation dynamics during the life cycle of the liverwort Marchantia polymorpha. We isolated thalli and meristems from male and female gametophytes, archegonia, antherozoids, as well as sporophytes at early and late developmental stages, and compared their DNA methylation profiles.

Results

Of all cytosines tested for differential DNA methylation, 42% vary significantly in their methylation pattern throughout the lif
